Even with the correct 302 motor mount stands, I had to redrill the frame and crossmember and move them forward for the drivers side head to clear the firewall. I cut out the floor hump and got a bolt on cover to clear the C6. Headers are still a challenge I haven't solved yet. Just some thoughts.
Try to find the most rust free truck you can find. That's the biggest challenge.

Minor adjustment so I wouldn't say 351W fitment was a problem though. I used a C4 so I had no problem with a low hump and I used the original trans crossmember just drilled new holes in the frame.. I've just used the stock exhaust manifolds, no headers.
